NORTHGLENN, Col. - A small plane crashed into a Northglenn, Col. home Monday afternoon, setting the plane and house on fire.

It happened around 3:30 p.m. near West 104th Avenue and Huron Street in Northglenn.

The pilot of the aircraft was able to walk away from the crash. Authorities say no one was home inside the house at the time of the crash. There were no other injuries.

A witness told 9NEWS the plane was pulling a banner ad and appeared to be struggling to keep the banner in the air. Sunny said he was traveling eastbound on West 112th Avenue when he saw the plane. He said the plane was high up in the air while the banner ad was low to the ground. He said the plane made a "U-turn" and then he saw smoke.

The plane crashed into the back of the home. The aircraft appears to be on its side, with the left wing sticking out from the roof of the two-story home. The view from Sky9 shows a large plume of smoke coming from the scene while fire crews battle the flames from the inside of the house.

Neighbors said they heard what they believed was a lawn mower and then an explosion sound.

Although the crash is near Rocky Mountain Airport, officials with the airport said the plane did not take off or was scheduled to land.
